You love riding your bike but it’s just too dang cold to go ride.  Afraid your cycling heart, lungs and muscles are starting to deteriorate over the lack of movment and all that good holiday food? There are a number of options you can ”exercise” to continue your cycling while indoors. If you want to continue to ride your personal bike but don’t want to go outside you can consider a Stationary trainer or a Roller.
Stationary Trainers allow you to ride and pedal your bike in a  stationary position.  This type of trainer you set and lock your rear wheel into position and pedal away. This system allows you to push yourself more because you are locked in place. There are a few types and styles of stationary trainers which come in differanct price ranges.
Another system you can use is the Roller Trainer. With the roller type both your wheels will be turning under your power, you will also have to balance which simulates a more realistic ride.
